Mass spec pogil

Mass spectrometry is a powerful analytical technique used to measure the mass-to-charge ratio (m/z) of ions in a sample. It is commonly used in various fields such as chemistry, biochemistry, and forensic science to identify and characterize compounds. In a mass spectrometer, the sample is ionized and then separated based on their m/z values.
